A kind of incomplete dock wallboard and job practices
Technical field
The present invention relates to a kind of building board, specifically a kind of incomplete dock wallboard and job practices.
Background technology
The dock wallboard for building of prior art comprises side fascia and inner wall panel, all is complete dock structure, namely the docking projection of a wallboard just in time cooperate wallboard with another the complete inlay card of docking recess together.Because complete inlay card, the cooperation place can not add the constructional materialss such as jointing material and anticracking material.After building completion, owing to the reason such as expanding with heat and contract with cold, the crack can appear in the joint of wallboard, and this crack can't eliminate fully by incrustation, affects attractive in appearance.
Summary of the invention
Technical assignment of the present invention is for the deficiencies in the prior art, and a kind of incomplete dock wallboard and job practices are provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of incomplete dock wallboard, comprise the wallboard body with heat insulation function, the two ends of wallboard body are respectively arranged with docking projection and docking recess, and the thickness of docking projection is less than the width of docking recess, has the first shoulder between described docking projection and the wallboard body, the lateral surface of docking recess has the second shoulder, and after two blocks of wallboards docked mutually, wherein the second shoulder of the first shoulder of a wallboard and another piece wallboard formed a semi-open gap.
Described wallboard body comprises enhancement Layer and insulation layer, and insulation layer is rectangular structure, and enhancement Layer is coated on the outside of insulation layer.
The cross section in described gap is triangular in shape.
A kind of job practices of described incomplete dock wallboard, the method is carried out according to following steps:
1) the docking projection with a wallboard is inserted in the docking recess of another piece wallboard, and after inserting fully, the first shoulder of first block of wallboard and the second shoulder of another piece wallboard form a semi-open gap;
2) smear the first jointing material in this gap, the volume of the first jointing material accounts for 1/3-2/3 of whole clearance volume;
3) smear anticracking material in the first jointing material outside, fill up whole gap, and with two wallboard levellings.
In order to improve the bonding strength of two blocks of wallboards, before two wallboard docking, smear the second jointing material in the docking projection of two blocks of wallboards and the cooperation place of docking recess first.
Described the second jointing material selects excellent adhesive mortar and polyurethane.
In order to improve the bonding strength of two blocks of wallboards, in to the first jointing material work progress in the gap, add connecting material.
Described connecting material preferred grid cloth.
Described the first jointing material is adhesive mortar, and described anticracking material is anticracking grout.
A kind of incomplete dock wallboard of the present invention and job practices compared with prior art, the beneficial effect that produces is:
1) incomplete dock wallboard of the present invention is reasonable in design, simple in structure, owing in the gap that the shoulder of the cooperation place of two blocks of wallboards forms, add jointing material and anticracking material, thus solved the problem of Cracking of wallboard under the environment that expands with heat and contract with cold.
2) job practices of the present invention is simple, links together by the wallboard of the jointing materials such as adhesive mortar or polyurethane with two docking, has improved the bonding strength of two blocks of wallboards.

Among the figure, 1, the wallboard body, 1-1, enhancement Layer, 1-2, insulation layer, 2, the docking projection, 3, docking recess, 4, the gap, the 5, first jointing material, 6, anticracking material, the 7, second jointing material, 8, connecting material, the 9, first wallboard, the 10, second wallboard, a, the first shoulder, b, the second shoulder.
The specific embodiment
Explain below doing below in conjunction with accompanying drawing 1, the 2 pairs of a kind of incomplete dock wallboards of the present invention and job practices.
Shown in accompanying drawing 1,2, a kind of incomplete dock wallboard of the present invention, its structure comprises the wallboard body 1 with heat insulation function, described wallboard body 1 comprises enhancement Layer 1-1 and insulation layer 1-2, insulation layer 1-2 is rectangular structure, and enhancement Layer 1-1 is coated on the outside of insulation layer 1-2.The two ends of wallboard body 1 are respectively arranged with docking projection 2 and docking recess 3, and the thickness of docking projection 2 is less than the width of docking recess 3, has the first shoulder a between described docking projection 2 and the wallboard body 1, the lateral surface of docking recess 3 has the second shoulder b, and after two blocks of wallboards dock mutually, wherein the second shoulder b of the first shoulder a of a wallboard and another piece wallboard forms a semi-open gap 4, and the cross section in gap 4 is triangular in shape.
The job practices of above-mentioned incomplete dock wallboard, as shown in Figure 2, can adopt following methods to carry out:
Embodiment 1:
The method is carried out according to following steps:
1) the docking projection 2 with the first wallboard 9 is inserted in the docking recess 3 of the second wallboard 10, after inserting fully, the first shoulder a of first block of wallboard and the second shoulder b of another piece wallboard form a semi-open gap 4, the cross section in gap 4 is triangular in shape, it is also passable to be other shape, but needs to consider whether construction is convenient;
2) in this gap 4, smear the first jointing material 5, preferred adhesive mortar, the volume of the first jointing material 5 accounts for 1/3-2/3 of whole clearance volume;
3) smear anticracking material 6 in the first jointing material 5 outsides, preferred anticracking grout fills up whole gap 4, and with two wallboard levellings.
Embodiment 2:
The method is carried out according to following steps:
1) with before the first wallboard 9 and 10 docking of the second wallboard, smears the second jointing material 7 in the docking projection 2 of two blocks of wallboards and the cooperation place of docking recess 3 first, can select adhesive mortar or polyurethane;
2) the docking projection 2 with the first wallboard 9 is inserted in the docking recess 3 of the second wallboard 10, after inserting fully, the first shoulder a of first block of wallboard and the second shoulder b of another piece wallboard form a semi-open gap 4, the cross section in gap 4 is triangular in shape, it is also passable to be other shape, but needs to consider whether construction is convenient;
3) in this gap 4, smear the first jointing material 5, preferred adhesive mortar, the volume of the first jointing material 5 accounts for 1/3-2/3 of whole clearance volume;
4) smear anticracking material 6 in the first jointing material 5 outsides, preferred anticracking grout fills up whole gap 4, and with two wallboard levellings.
Embodiment 3:
The method is carried out according to following steps:
1) with before the first wallboard 9 and 10 docking of the second wallboard, smears the second jointing material 7 in the docking projection 2 of two blocks of wallboards and the cooperation place of docking recess 3 first, can select adhesive mortar or polyurethane;
2) the docking projection 2 with the first wallboard 9 is inserted in the docking recess 3 of the second wallboard 10, after inserting fully, the first shoulder a of first block of wallboard and the second shoulder b of another piece wallboard form a semi-open gap 4, the cross section in gap 4 is triangular in shape, it is also passable to be other shape, but needs to consider whether construction is convenient;
3) in this gap 4, smear the first jointing material 5, preferred adhesive mortar, the volume of the first jointing material 5 accounts for 1/3-2/3 of whole clearance volume, in to the first jointing material 5 work progresss in the gap 4, add connecting material 8, preferred grid cloth, grid cloth can be dosed between inside and outside two-layer adhesive mortar;
4) smear anticracking material 6 in the first jointing material 5 outsides, preferred anticracking grout fills up whole gap 4, and with two wallboard levellings.
